🚀 go-pugleaf

I am trying to install GNU emacs 18.57 on a VAX running USG5-3.
In addition we have TCP/IP extent. (i.e. sockets and ptys).
I added 
#define HAVE_PTYS
#define SYSV_PTYS
#define HAVE_SOCKETS
to the config.h file

The problem is that when create_process() is run its call to
allocate_pty() fails to find a single available pty to open.
Since setpgrp() is called the child process created will not
have a controlling tty.
The error returned from the open on the pty depends on whether you
are root or not. If you are root every open returns a 5. [EIO]
As a normal user it will return a 5 on the first attempt, and
a 13 [EACCESS] on all other ptys.  The directory name and file
name supplied to the open is correct.

This means when I type m-x shell, the shell has no controlling tty
and thus the UNIX command ps returns an erro
"can not find controlling terminal".

I think this is also causing some other problems.

Has anyone compiled or used GNU emacs on a VAX running USG5-3 or
have any explaination of a possible solution
